2 Claims.

The invention relates to lamp shades of the type having what may be termed corrugated body portions. As heretofore made, these shades have been provided with a supporting ring carrying an initially flat and continuous paper sheet that is provided with a series of tapering inwardly-extending folds or scorings which cause said sheet, when curved to form a shade, to assume a conical shape. 1 1

The new shade, herein disclosed, is made from separate small pieces of paper. These pieces are individually shaped before or while they are being assembled, so that, when assemb1ed,-the resulting shade will present a corrugated appearance. By thus using small pieces of paper as elements of the completed shade, it is possible to cut them from otherwise useless scrap material and, consequently, reduce the manufacturing cost.

The invention will best be understood if reference be had to the accompanying drawing,

in which Figure l is a view of the shade in elevation;

Figure 2 is a plan view of said shade;

Figure 3 is afragmentary sectional View to 25 an eg larged scale taken on the line 3--3'of Figure Figure 4 is a fragmentary view showing how adjacent elements of said shade are united, and

Figure 5 shows slitted and removable sections of the shade.

Refering to the drawing, I and 2 are rings of wire, or other suitable material, which impart rigidity to the shade. To the upper ring I is secured a spider 3 from which the shade, as a 35 whole, may be supported.

The individually curved and tapered pieces of paper 4 are overlapped at their contacting edges 5, where they are united by an adhesive 6, and these pieces 4 are each, at these edges, provided 40 with upper and lower perforations l, 8, through which the rings I, 2 extend, spacers 9, I0, through which said rings I, 2 also extend, being employed to maintain the shape of the individual pieces of paper 4, and to stiffen the shade as a whole.

I If the individual parts 4 of the shade are to be severed from an original sheet of paper, that sheet should be cut on diagonal lines in order to produce alternately tapered portions.

By the use of separate pieces of paper new 50 decorative effects are possible and if desired, these separate pieces may be dissimilar from each other in color, design or other characteristics.

Instead of uniting the edges 5 with an adhesive, these same edges may be united by eyelets, wire ll staples, brads, rivets, removable clasps I2, or

other suitable fasteners. The spacers 9, III, equally space the panels, and give to all of the individual panels the same curvatures. The curvature of the flutes may be varied by the number of panels in any particular size of the rings 5 9, Ill.

The spacers 9 and Il) may be tubing (spaghetti) of the type used in the insulation of electric conductors, or suitable paper tubing or straws that can be curved slightly without break- 10 ing, these spacers of either ring being of the same length when it is desired to have the panels all curved to the same extent. If, however, variations in the curves of these panels are desired for decorative efiects in the finished shade, the curvatures of the panels will be controlled by the length of the spacers.

In the modification shown in Figure 5, the individual sections of the shade have slits II communicating with the perforations I, 8, the 0bject of these slits being to permit the removal and. replacement of such of said sections as may have i become damaged or discolored. In such a construction, either the rings 9, III will constitute the only means for holding the sections of the shade in place, or the devices for uniting the proximate edges of the sections will be detachable clasps I 2, or other separable devices. In some instances it may be possible to use an adhesive substance which will adequately hold the edges of the shade sections together, and yet may be readily broken when a damaged section is to be replaced by a new section.

Having thus described my invention, what I claim is.

1. A fluted lamp shade comprising a plurality of curved and separate pieces of sheet shade material respectively adjacent at their longitudinal edge portions, each of said curved pieces comprising one flute of the shade and having its 40 curved mid-portion projecting outwardly radially of the shade and having its inner edges substantially in alignment with the inner edges of adjacent ones of said curved pieces, a circular retaining member extending through the inner and adjacent edge portions of said curved pieces, said curved pieces having apertures therethrough to receive said retaining member, and a tubular spacing member on said retaining member between the edge portions of each of said curved edge portions are held respectively in close engagement with each other around said apertures thereby concealing said retaining member from external view and stiffening said shade, each of said edge portions having a slot from its inner edge into the corresponding aperture facilitating the removal and replacement of any desired fluted piece Without disturbance of the rest of the shade structure.

2. A fluted lamp shade comprising a plurality of curved and separate pieces of sheet shade material respectively adjacent at their longitudinal edge portions, each of said curved pieces comprising one flute of the shade and having its curved mid-portion projecting outwardly radially of the shade and having its inner edges substantially in alignment with the inner edges of adjacent ones of said curved pieces, a circular metallic ring extending through the inner and adjacent edge portions of said curved pieces, said curved pieces having apertures therethrough to receive said ring, and a tubular spacing member on said ring between the edge portions of each of said curved pieces, the combined length of said spacing members and thickness of said edge portions on said ring being equal substantially to the circumferential length of said ring, whereby the outer surfaces of said contacting edge portions are held respectively in close engagement with each other around said apertures thereby concealing said ring from external view and stifiening said shade, each of said edge portions having a slot from its inner edge into the corresponding aperture facilitating the removal and replacement of any desired fluted piece without disturbance of the rest of the shade structure.
